Note: Commissioned by the Emperor Justinian, built in Constantinople in the 6th century. The structure, a domed basilica, was built in the amazingly short time of about six years, being completed in 537 CE. The architects were Anthemios of Tralles and Isidore of Miletus.For over 900 years it was Christendom's grandest place of workship; after the fall of the city to the Ottomans (1454), it became one of the principal mosques of Istanbul for almost 500 years.
